They questioned the person Friday, then they released the shooter. Police, however, have not said why the person, whom they describe as "the shooter" and not a suspect, was released.

Police said there is no threat to the public because this was not a random act, according to a news release published Friday and another one published Monday.

The person shot Summers in an alley north of Virginia Street, and Summers ran south, across the street, collapsing at the alley entrance on the south side of the street, according to limited information released by police and the accounts neighbors shared with the Journal & Courier on Friday.

Neighbors heard one shot, which Tippecanoe County Coroner Donna Avolt confirmed Friday, when she noted that Summer was shot once in the chest.

Police performed CPR on Summers when they arrived, and paramedics rushed him to a local hospital, where he was pronounced dead.

A neighbor said police armed with rifles surrounded a house on Ninth Street south of Virginia Street and removed four people from that house at gunpoint.

Lafayette police declined Monday to elaborate on this as well as other questions about the factual circumstances surrounding this shooting.
